The SLCD bus clock (CLK_SLCD_APB
) must be enabled to access
the registers and it can be configured in the Main Clock module MCLK,
A 32.768kHz oscillator clock (CLK_SLCD_OSC
) is required to
clock the SLCD. This clock must be configured and enabled in the 32KHz oscillator
controller (OSC32KCTRL
) before using the SLCD.
